ber 33 formed in the plate 25. A valve 34 is slidably mounted withinsaid chamber 33 and is provided with an enlarged seat adapted to be heldnormally, by a spring 35, against a suitable valve seat formed on thepacking plate 25, or, as shown, upon a bushing 36 held in the centralbore of said plate. The valve chamber 33 communicates through a smalllaterally evtending` port or conduit 37 with the space defined betweenthe front face of the plate 25, the rear of the cylinder bead`17 and thecylinder 16.

Fluid under pressure from any suitable source thereof, as, for example,the main air tank of the locomotive, is admittedV into the interior ofthe cylinder 16 rearwardly of the piston 15 through an inlet 38; saidinlet communicatingl with a screwthreaded boss 39 into which is threadedthe end of a pipe 40, leading to said pressure.

l\[ounted within a lateral extension 42 formed upon the piston 15 is avalve 43. Said valve 43, as shown, is of the poppet type, the

enlarged head of which engages with a valve 3. seat preferably formed ona bushing 44 seated within a` suitable bore provided within said lateralextension 42. The valve 43 is guided for sliding movement by a stem 45and valve rod 46 preferably made integral with the valve. The stem 45passes through a. central aperture in a cap 47 screwed into the end ofthe bore formed in the extension 42. Coiled about the stem 45 is aspring 48 the ends of which abut against the valve cap 47'and theenlarged head of the valve 43 for holding the valve normally in itsclosed or seated position. The space within the bore of the extension 42and between the valve 43 and the valve cap 47 communicates through asmall lateral port 49 with the interior of the cylinder 16 rearwardly ofthe piston 15.`

Communicating with that part of the bore of the extension 42, whichforms the chamber for the valve 43, and forwardly of said valve is alateral conduit 50, which communicates at its end through a branchconduit l (see Fi 3) with a valve chamber 52, in which is seated a checkvalve 53 normally held in closed or seated position by a spring 54. Thecheck valve 53 is located adjacent to the end of a longitudinallyextending conduit 55, (see Fig. 4) which passes through the piston andplate 25 and communicates at its front end with the space between thepacking plate and front cylinder head 1.7. 'il ireaded upon the outerprojecting rear end of the hollow rod 27 is a connecting member 56which, as shown, is in the form of a U-shaped member, the legs of whichterminate in interior-ly threaded bosses, one of which is screwed uponthe rod 27 and the other upon the front end of a compensating' reach rod57. At its rear end the latter is secured to the usual throttle lever 58which in accordance with the usual practice is provided with a springpressed latch 58a adapted to engage with the teeth of a toothed quadrant59. The reach rod 57 is preferably constructed so that it will becompensating` for temperature changes, and as shown, may consist of tworod sections 57 n and 57 b, the section 57 a being connected at itsfront end to the member 56 and at its rear end to the pivoted lever 57C,while the section 571 is connected at its rear end to the throttle lever58 and at its front end to said lever 57 c.

The rear end of the rod 29 projects beyond the hollow rod 27 and hasscrewed upon it a pair of adjusting nuts 60 which nuts, as clearly shownin Fig. 2 of the drawing, are seated within the space spanned by thelegs of the U-shaped connecting member 56. rlhe rod 29 projects slightlybeyond the nuts 60 and is of non-circular cross section for engagementwith a similarly shaped bore or recess provided in the rear boss of saidmember 56: the purpose of this construction just described being to holdthe rod 29 again st rotation when the nuts 60 are adjusted.

lt will be noted by referring to Fig. 2 of the drawings that the ends27a and 29;L of

Vthe rods 27, 29 respectively, are seated within the counter-bore 28 ofthe piston 15 and that they are located between t-he front end of thevalve rod 46 of the valve 43 and the rear end of the valve 34. The rods27, 29 are arranged to move normally as an integral structure, thedistance between the rear face of the end 27 a and the front face of theend 29a is adapted to be adjusted by means of the nuts 60. The nuts 60should be so adjusted that the engaging faces of the end 27a and the end29a with the valves 43 and 34 respectively will lie between the frontend of the valve stem 46 and the rear end of the valve 34 with a slightamount of clearance as indicated in Fig. 2, the purpose of whichclearance will appear more fully from the following description ofoperation.

The manner in which the device operates is as follows: Let it be assumedthat air or other iiuid under pressure is delivered through the pipe 40and port 38 to the interior of the cylinder 16 and to the rear of thepiston 15. Let it also be assumed thatthe throttle lever is set in thethrottle closed position. If now the engineman wishes to open thethrottle, the latch 58El is unlatched and the throttle lever is pulledrearwardly in the usual manner. This movement of the throttle lever iscommunicated through the compensating lever reach rod 57 and connectingmember 56 to the rods 27, 29, both of which are therefore also movedrearwardly or from right to left, as Vshown in Fig. 2. After but a veryslight movement of the rods 27, 29 in the direction described, theengage-ment of the enlarged head 27 with the front end of the valve rod46, will canse the valve 43 to be moved rearwardly against tlieaction ofthe spring s `The :valve 43' obviously will move off-its seatand thefluid underypressurewithin thecylinder 4lo will flowfithr'ougll theconduit `49 past` thewalve L3 and. through the conduits 50: and 5l.`IThe check valveV 52 will be raisedofi'` its seatgand the `fluid `willflow. througlithe `conduit `55 to the space atthe front end of thecylinder 16 between `thefront `cylinder headl 11-7 and the packingretaining plate 25.

The liftingy of the valve Btolf its seat will,

as above described,

`permit the' 4"fluid to *escape fromthe space .in

front of the'fpiston `l5 andlretainig .plate 25.

As the space `to the `rear of' :the piston `l5` is always `underpressure,fthe piston willthere' forwardly, its movement is followedby aforward 'movement ofthe `"throttle 'lever and,

y as `with the opening movement ofthe throttle,

it is necessary for 4the engineman fto `exert merely suilicient pressureto' hold'fthe valve 34 offfitsseatmf: q il l 1 1 :Should the device failto function to oper! ate fthe throttle valve by powerbecause of "afailure of `the -fluid pressure supply `toV the cylinder 16, or fory anyotherr cause, the com struction permits the manialoprationi of the`piston `15 and therefore offthe throttle valve. It willfbe `notedthatthehead Welisof-.quite substantialiconstuctionfand thatbii-t a slight a 1nthe spacebetween"theyfront cylinder head U5 fore travel forwardly."Asthepistonmovcs amount of rearward movement thereof can occur withinthe space defined between the inner end of the counterbore 28 and therear wall of said head before the latter will engage the inner end ofthe counterbore 28. lVhile when the throttle lever is moved forwardlythe small clearance between the forward end of the connecting member 56and the end of the piston rod 14 will permit but a slight amount offorward movement .before the front face of said member 56 will engagewith the rear end of the piston rod 14. yIf therefore the fluid pressureis ineffective and the desired movement of the piston is not broughtabout by the unseating of either the valve 43 or the valve 34, as thecase may be, it will be seen that the engineman may, by exertingsufficient force, open or close the throttle valve solely by manualeffort.

It will be noted that the effective area presented by the rear face ofthe piston 15 is less than the effective area furnished by the frontface of the retaining plate 25. Conse` quently when the piston is atrest, the pres` sure per unit of area exerted aga-inst tlie lattersurface will necessarily be less than that exerted upon the formersurface.

It will be noted that the construction herein disclosed hasveryimportant advantages in that only two packing cups are required. Nospring is required for returning the piston to the throttle closedposition. The number of moving parts are but few and such parts are ofcompact, sturdy construction. The device is therefore of small compact.durable construction capable of being manufactured at a .low cost andfurthermore maintenance costs due to breakage, etc., are reduced to aminimum. It will be perfectly obvious that the two part construction ofthe rods 27, 29 may, if desired, be dispensed with and a rod of one partconstruction be substituted therefor. The two part rod constructionshown however, permits the clearance space .4 hereinbefore referred to,to be adjusted from the exterior of the cylinder. Similarly thecompensating reach rod construction shown, may be replaced without anychange whatsoever in the construction of the other parts, by a singlerod, such as shown in the co-pending McKee application. The use of theformer is preferred, because increase or decrease in the length of therod sections 57a, 57b due to temperature changes will merely result inproducing a rotation of the lever 57C upon its pivot without causing anymovement of the throttle valve. It will likewise be understood Vthatmany other changes, variations and modifications may be vresorted'towithout departing from the spirit of the invention, for example; while Ihave described the apparatus as being in the throttle closed positionwhen thek parts are as shown in the drawings or in other words, when thepiston 15 is at the right hand end of the cylinder it will be obviousthat the closed throttle position could be effected when the piston isat the left hand end of the cylinder such a change being` effectedmerely by changing the position of the arm 11 on the shaft 10. In suchcase it will be understood that then the piston would move from right toleft for closing and from left to right for opening the throttle.
